Structure of the present utility model, be applicable to the control of hot water apparatus such as water heater, water dispenser, sterilizing machine, the temperature-adjusting device of other working fluids combines with this structure, only need to increase the parts such as shell of a special-purpose, also can reach the hot water effect of above-mentioned automatic constant temperature and pressure, and be not limited to the structure of a certain hot water apparatus.Such conversion all drops within protection scope of the present invention.
Referring to Fig. 2, the circuit diagram that this is routine: form by low pressure adapter circuit, temperature sensor circuit, IC control motherboard circuit, A.C. contactor circuit, primary heater circuit and peripheral circuit.In the low pressure adapter circuit, the voltage of positive 12V that the lower pressure rectifier filtering that low pressure adapter 12 is lowered into main power source 15, IC5 voltage stabilizing obtain and negative 12V etc. is delivered in the IC control mainboard 13.IC1 is to convert the sample temperature parameter to be directly proportional with temperature voltage in temperature sensor circuit.The higher-order of oscillation modulation circuit that IC control motherboard circuit is made up of IC2, IC3, IC4 and resistance R 15, R16, R17, inductance L 1, L2, L3, triode Q1, wherein, IC2 is a thermostat temperature lower limit comparator, IC3 is a thermostat temperature upper limit comparator, and IC4 is the Task Switching device that the voltage transitions that the thermostat temperature bound is sent here is become the voltage of drive motors positive and reverse steering and rotating speed.The bleeder circuit that resistance R 15, R16, R17 form, through the base bias that L2 provides for triode Q1, fine setting R15 makes triode Q1 conducting, and the LC oscillator rises and swings.When coil L1, the L2 of the magnetic core arrival water pressure detector 6 in being placed on water inlet pipe, L3, the LC oscillator rises and swings aggravation, induction L3 by magnetic core obtains induced voltage, the pull-in winding that makes relay K 1 is the triode Q3 conducting of load, the K1 closure, at this moment, the normally-closed contact that finishes K1 send electricity to control the process of mainboard 13 to resistance R 30 IC that goes to reset, the voltage adhesive K2 of the pull-in winding of relay K 2 because of obtaining sending here from K1, the closure of K2 provides the pick-up voltage loop for the A.C. contactor circuit and adhesive K3 enters the voltage of duty.
Referring to Fig. 3, the circuit block diagram that this is routine.After the present embodiment energising, normal-temperature water enters through water inlet 1, low pressure adapter 12 is sent 12 volts low pressure to IC control mainboard 13, numerical value display screen 11, the bar magnet of establishing in the water inlet pipe cavity is dashed by certain hydraulic pressure, at this moment, the coil that is installed in outer water pressure detector 6 is delivered to detected parameter in the IC control mainboard 13, and IC controls mainboard 13 by pressure parameter being analyzed comparison and calculating, instructs each parts again.
If when meeting safe starting hydraulic pressure, the 13 commands relays work of IC control mainboard, A.C. contactor 7 is closed because of the voltage that obtains sending here from relay, thereby 380 volts main power source is delivered to primary heater 9, and heating work is carried out.Temperature sensor 10 is gathered hydraulic pressure, voltage, entry variation of temperature parameter at any time, the parameter of gathering is in time fed back to IC control mainboard 13, after the parameter comparison that is configured by 13 pairs of mainboards of IC control is calculated, send one group in order to control the alternating voltage of 3 volts of micro machine direction of rotation and speed, 3 volts of micro machines 3 by speed change assembly 2, be subjected to temperature to control forward and reverse adjusting flow control valve 5, control the discharge that enters primary heater 9, guarantee to reach the purpose of the dynamic constant temperature and pressure of design temperature in real time through the water temperature of primary heater 9.
When if the hydraulic pressure value that water pressure detector 6 gets is lower than setting range, A.C. contactor 7 receives the cut-offing instruction of IC control mainboards 13, realizes protecting automatically shutting down; If hydraulic pressure is higher than setting range, current enter after the water inlet 1, are dammed by mechanical permanent flow valve 4, hydraulic pressure are controlled at the upper limit of setting range, to reach the purpose of safe handling.When the probe value of temperature sensor 10 is within desired temperature, the heater operate as normal; If temperature sensor 10 was given the dynamic constant temperature IC control of intelligent liquid mainboard 13 with feedback information when temperature was below or above desired temperature, IC control mainboard 13 sends instruction, by micro machine 3, speed change assembly 2 and be subjected to temperature to control forward and reverse adjusting flow control valve 5 to realize reducing of corresponding discharge or increases, thereby make the water temperature rising or drop between the set temperature value.
If when being lower than safe starting hydraulic pressure or water inlet 1 internal memory air being arranged; IC in the IC control mainboard 13 can instruct the shutoff relay current; so that the voltage of the pull-in winding of A.C. contactor 7 cutout; thereby cut off the power supply of giving primary heater 9; at this moment; numerical value display screen 11 reaches the purpose of safeguard protection to owe the indicating reminders user of hydraulic pressure, has avoided the gas explosion of HTHP to take place.
When voltage descends, the power of primary heater 9 must descend, parameter feedback by temperature sensor 10, IC control mainboard 13 is made the instruction of dwindling output to 3 volts of micro machines 3, come by-pass valve control dwindling discharge by speed change assembly 2, thereby make the temperature of delivery port 14 rise to the temperature value of setting.When voltage was higher, said process was opposite, reached the constant temperature effect that not influenced by voltage pulsation.
